Installing an older version of DSE

Summary

When installing an older version of DSE the user will see errors about unmet dependencies.

Symptoms

You may get the following dependency error on Debian or Ubuntu:

The following packages have unmet dependencies:
dse-full : Depends: dse (= 3.0.2-1) but 3.0.4-1 is to be installed
 Depends: dse-hive (= 3.0.2-1) but 3.0.4-1 is to be installed
 Depends: dse-pig (= 3.0.2-1) but 3.0.4-1 is to be installed

 Depends: dse-libmahout (= 3.0.2-1) but 3.0.4-1 is to be installed
E: Unable to correct problems, you have held broken packages.

Cause

This is how "apt" works when you have package dependencies. It will pick the latest version that's available unless a version is explicitly specified

Solution

In order to install an older version, you must specify the desired version of all of the dependencies as well as for the dse-full package itself. For example, to install DSE 3.0.2-1, use the following command:

sudo apt-get install dse-full=3.0.2-1 dse=3.0.2-1 dse-hive=3.0.2-1 dse-pig=3.0.2-1 dse-demos=3.0.2-1 dse-libsolr=3.0.2-1 dse-libtomcat=3.0.2-1 dse-libsqoop=3.0.2-1 dse-liblog4j=3.0.2-1 dse-libmahout=3.0.2-1 dse-libhadoop-native=3.0.2-1 dse-libcassandra=3.0.2-1 dse-libhive=3.0.2-1 dse-libpig=3.0.2-1 dse-libhadoop=3.0.2-1

This is already covered in the documentation for example installing previous versions to DSE4.6
